Evaluation on the efficacy of post-op early enteral nutrition in rectal cancer patients
Van Hieu Nguyen, Van Quang Le*, Le Huy Trinh, Trung Bach Tran
Department of Oncology, Hanoi Medical University
Received 25 December 2016; accepted 6 March 2017

Abstract:
Patients and methods: 60 rectal cancer patients who had been gone through the rectum amputation surgery (Miles or
Hartmann procedure) were randomized into 2 groups: post-op early enteral nutrition or post-op parenteral nutrition.
Result: good tolerance rate was 83.3%. Gas passing time of the early enteral nutrition group was shorter than the remaining
(2.4 days vs 3.1 days), so were the hospitalization stay (12.9 days vs 14.8 days) and hospitalization cost (220,000 VND/day vs
366,000 VND/day). Conclusions: post-op early enteral nutrition in rectal cancer patients is safe, efficacy, and economic in
comparision to conventional parenteral infusion.
Keywords: Post-op early enteral nutrition, rectal cancer.

Results of adaptation rearing for Landrace,

Yorkshire and Duroc varieties imported from France, USA and Canada
Hong Son Trinh*, Duy Pham Pham, Hun Hung Dinh, Quang Tuyen Trinh
National Pig Research and Development Center
Received 14 November 2016; accepted 3 January 2017

Abstract:
This study was conducted in Kyson Pig Nuclear Herd Development and Research Station belonging to Thuy Phuong Pig
Research Center, National Institute of Animal Sciences from September 2015 to October 2016 in order to evaluate the
results of adaptation rearing with 90 pigs imported from France (Landrace: 40 sows and 5 boars; Yorkshire: 40 sows and 5
boars), 140 pigs imported from the US (60 sows and 10 boars of Landrace breed; 60 sows and 10 boars of Yorkshire breed),
and 60 Duroc pigs imported from Canada (50 sows and 10 boars). The initial research results showed that Landrace,
Yorkshire, and Duroc pigs imported from France, US, and Canada have adapted in Vietnam with the proper growth and
reproduction. The average body weight gain in the period of from 40 kg to 100 kg of Canada Duroc breed was 953.96 g/
day, followed by the American Landrace, French Landrace, French Yorkshire breeds, and the lowest was the American
Yorkshire (868.07 g/day). The initial estrus age of Yorkshire and Landrace breeds imported from France (177.74 and
172.93 days) was earlier than that imported from America (200.63 and 213.25 days); Duroc imported from Canada had
the initial estrus age of 188.96 days, earlier than that of Landrace and Yorkshire imported from America but later than
Landrace and Yorkshire imported from France. Landrace and Yorkshire breeds imported from France and America had
high potential reproduction; the number of newborn piglets in the first parity was from 11.90 to 15.36. The body weight
gain of Canadian Duroc breed was high, but the number of newborn piglets in the first parity was low, about 9.87 piglets/
litter. The number of survival newborns of Landrace and Yorkshire breeds was from 10.17 to 13.42 piglets/litter, while that
of Duroc breed reached 7.84 piglets/litter. The number of weaned piglets of Yorkshire imported from France was highest
with 12.32 piglets/litter; the number of weaned piglets of French Landrace, American Landrace, and American Yorkshire
varied from 9.36 to 9.66 piglets/litter; and that of Duroc was lowest with 7.0 piglets/litter. The survival body weight was
from 1.43 to 1.56 kg/piglet, weaned weight was from 6.41 to 6.76 kg/piglet.
Keywords: Adaptations rearing, Duroc pig, Landrace pig, pig farming, Yorkshire pig.
